2023-08-19consolidate u-boot/seabios/coreboot build scriptsLeah Rowe
See file: resources/scripts/build/defconfig/for It is based on: resources/scripts/build/payload/u-boot The u-boot payload script has been deleted, as has the seabios payload script; the build/boot/roms logic has been heavily simplified too, by removing the logic for building of elf files based on defconfig. SeaBIOS, U-Boot and coreboot all use defconfig-type infrastructure for their build systems, and they are fundamentally the *same* in how to compile each codebase, at least in an lbmk context, regardless of actual (and very huge) differences in these codebases. Several hundred sources-lines of code have been eliminated by this change, drastically simplifying everything; U-Boot payload compiling also now errors out when a single build fails, instead of continuing. Also: build/boot/roms no longer re-compiles a coreboot target that was already compiled, which is the same behaviour observed for payloads. (this means you must now manually delete a target, when you wish to re-build it; the build/boot/roms logic now more or less just runs cbfstool; blobutil is handled from build/defconfig/for) ALSO: Since crossgcc is now handled by build/defconfig/for, not build/boot/roms, standalone compiling of u-boot is now possible. This has been tested. You compile it like so: ./build defconfig for u-boot or specific trees, e.g. ./build defconfig for u-boot default One other consequence of this patch is that re-building the same ROM image is now much faster, because the same builds are re-used unless deleted. This could be useful when testing grub.cfg changes, for example, if that's all you change. With things like ccache used (not yet used robustly in lbmk), this could speed things up more, depending on the codebase. This patch demonstrates the raw power of lbmk; it is a very simple and highly efficient build system, and now much more so! Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-17remove download scripts, consolidate into scriptLeah Rowe
most of them were just calling the gitclone script, so remove them. the grub script was treating gnulib as a dependency. i've now added the ability to grab 1 dependency, in the gitclone script (it should be expanded later to support multiple dependencies) the gitclone script has been renamed to "fetch". the "fetch_trees" script does more or less the same thing, but calls "fetch" and handles multiple revisions if a project needs that this is more efficient, and slightly reduces the code size of lbmk!

2023-06-13Revert "Remove most of Ferass's lbmk contributions"Leah Rowe
This reverts commit a4ea2867319471d9fe7d4ee540881e0286b4d3cf. The licensing audit has been abandoned. I will not be re-licensing in bulk to MIT. I can still use MIT license on new works, e.g. utilities, but there's really no pressing need to re-license lbmk. It's just shell scripts, and most of what it interacts with (coreboot, grub, seabios) is GPL anyway. So who cares? Ferass's patch was removed due to refusal to re-license, but the decision to re-license has been canceled. I'm now aiming for a quick stable release.
2023-05-27Remove most of Ferass's lbmk contributionsLeah Rowe
The primary purpose of my intense auditing has been to improve lbmk's coding style and fix bugs but there is a secondary purpose: know precisely who owns what, because I want to re-license as much as possible of lbmk under *MIT*, instead of the current GNU licensing. MIT is vastly superior, because it grants *actual* freedom to the user, permits *sublicensing* and it is vastly more compatible with other GPL combinations; for example, MIT license is compatible with GPL2-only whereas lbmk's current mix of GPLv3-or-later and GPLv3-only is legally incompatible with GPLv2-only. Re-licensing under MIT will most likely result in more contributions to Libreboot's build system in the future, especially as it will attract a lot more commercial interest. Contrary to the popular arguments, copyleft is a liability to the free software movement and results in less code being written; in practise, permissively licensed code gets more public contributions, including from commercial entities, even if companies can theoretically make something proprietary out of it (in practise, anyone inclined can just use the upstream and proprietary forks almost always die). Copyleft propaganda is fundamentally flawed. See: <https://unixsheikh.com/articles/the-problems-with-the-gpl.html> Anyway, I've been doing a combination of: * Seeking permission from other copyright holders, for re-licensing * Deleting, or moving, other contributions; for example, splitting certain contributions into separate files so that originally modified files become unencumbered. This latter solution is a result of *code cleanup* arising from the audit. For Ferass's contributions, I opted to seek *permission*, and permission was denied. In full compliance with this legal imperative, I'm acting accordingly; this commit removes all of Ferass's changes that converted lbmk to posix shell scripts, thus removing his copyright on the affected files, bypassing his authority entirely. Therefore, lbmk is largely now bash-dependent. In practise, nobody is going to use anything other than a GNU system to build Libreboot, because many projects that Libreboot makes use of rely heavily on GNU; for example, coreboot's build system makes heavy use of GNU-specific extensions in *GNU Make*, and likely contains many bashisms. Of course, Libreboot also compiles GNU GRUB. I would much rather have MIT-licensed Bash scripts than GPL-licensed posix SCL scripts. This reverts the changes from Ferass El Hafidi, for the following commits, with some exceptions: * 7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9 * f787044642236917c9c4dbcaa48a6b0648097db0 Exception: download/mrc not reverted, because that was already a fork of an existing script under coreboot's build system, and their script was GPLv2. i cannot/will not re-license this file (ergo, 7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9 change remains intact, on this file) resources/scripts/build/boot/roms_helper, these changes have been kept: * 7e6691e9 - Add ARMv7 and AArch64 support * dec2d720 - add myself in the build/roms_helper script (added 2021 copyright for the change below) * b7405656 - Workaround for grub's slow boot ^ these changes will be re-factored, splitting them out of the file into a new file. This will be done in a future lbmk revision. (in some cases, it makes sense to keep a change but split it, allowing the main file to be re-licensed without the change in it) This is part of a much larger series of licensing audits. It's likely that lbmk will be posix-compliant (in its shell scripts) again some day, because I'm planning to rewrite most of these scripts (the ones modified in this patch), and many of them (e.g. individual download scripts) are subject to future deletion in a planned overhaul of the download logic for third party projects. In addition: these changes are being kept (no attempt to re-license them will be made): * cff081c6 - Fix grub's slow boot (1 year, 5 months ago) <Vitali64> * 4c851889 - Add macbook*1 16mb configs (1 year, 6 months ago) <Vitali64> Ferass's work that remains will be split into dedicated files containing them, where feasible. In the case of grub.cfg (for GNU GRUB), I don't care because it's a script for an engine (GRUB shell) that's under GPL anyway, so who really cares about MIT license.

tianocore is a liability for the libreboot project. it's a bloated mess, and unreliable, broken on many boards, and basically impossible to audit. i don't trust tianocore, so i'm removing it.
